ASSESSING HYDROLOGICAL FLUCTUATIONS THROUGH SPACE AND TIME USING TIME-LAPSE IMAGERY

Variability of freshwater systems over space and time increases the difficulty of monitoring and understanding hydrological and environmental changes. Time-lapse imagery offers a passive technique of high-temporal resolution to monitor aquatic systems. With over forty time-lapse cameras installed across the Great Plains, the Platte Basin Time-lapse (PBT) project is a multimedia endeavor documenting a stressed watershed to contribute to scientific research, while simultaneously supporting science communication. We are exploring methods of streamlining visual and automated image analysis to understand hydrological fluctuations in relation to environmental variables at a range of temporal and spatial scales. We use batch image classification to quantify water inundation in ground-water fed lakes and sub-irrigated wetlands and employ time-series modeling to assess changing dynamics. In this presentation we present our preliminary findings, examples of time-lapse data sequences, and share ways that other researchers may engage with PBT. We invite you to explore more at www.plattebasintimelapse.com.
